Gmail's powerful filters have long been one of its strongest features, if you're willing to create and nurture them. Now a new Gmail Labs feature is giving every user a few pre-set Smart Labels to automatically catch bulk messages, service notifications, and mailing lists.

Google says that these new, automatically populated filters won't touch any filters you already have set up, and that they can be edited to increase or slim down their scope in your Filter settings.

Head into the Labs section of Gmail to search and enable Smart Labels (or click here). They may not be immediately available, but should arrive soon. Tell us how they're working in your own over-stuffed inbox in the comments.
